It also has a clear ring structure and large diffuse disk, resembling a giant donut. It may be the most distant collisional ring confirmed to date. The closest thing to it in the local Universe is the well-known Cartwheel Galaxy, also a collisional ring galaxy.<\/p>\n\n\n\n<p>The hole at its centre is three million times bigger than the diameter of the supermassive black hole in the galaxy Messier 87, which in 2019 became the first ever to be directly imaged.<\/p>\n\n\n\n<p>The team worked with colleagues from Australia, the United States, Canada, Belgium and Denmark. Spectroscopic data was gathered by the WM Keck Observatory in Hawaii and images recorded by NASA\u2019s Hubble Space Telescope to identify the unusual structure of the galaxy.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have found a rare and massive collisional ring galaxy from some 10.8 billion years ago that is forming stars 50 times faster than the Milky Way, says York University Postdoctoral Fellow Leo Alcorn of the Faculty of Science.<\/p>\n","protected":false},"author":1202,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","ngg_post_thumbnail":0,"footnotes":""},"categories":[6],"tags":[],"class_list":["post-1658","post","type-post","status-publish","format-standard","hentry","category-physics-astronomy"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
